Kıyak, S., Suludere, Z., 2021, A scanning electron microscope study of the sensilla on antenna and mouthparts in Eurygaster testudinaria (Geoffroy, 1785) (Hemiptera, Heteroptera, Scutelleridae)

ABSTRACT: In insects, there are many sensilla showing different structural features on the mouthparts and antennae. These sensilla act as the sensory organs of insects. Main functions of the sensilla in insects are chemoreception, mechanoreception, and thermohygrosensory properties. Eurygaster testudinaria (Geoffroy) (Hemiptera, Heteroptera, Scutelleridae) is a widespread species that is a perilous pest for agricultural areas. In this study, the sensilla on the mouth parts and antennae of E. testudinaria were investigated by using scanning electron microscope technique. In our results we obtained, we were identifed four types of sensilla such as sensilla basiconica, peg-like sensilla, sensilla trichodea, sensilla campaniformia. Each sensilla type were divided into subtypes and numbered. We hope to contribute to similar studies in the future to be carried out with this morphological study.
